Patent GB-2299643-A (GB)
Title: Clutch control system
Inventor: JONES CHARLES JOHN
IPC: B60W30/18
Filed: 1995-10-20
Abstract: A clutch control system for the automatic control of a motor vehicle clutch (14) which connects an engine (10) with a gearbox (12) under the control of a driver-operated gear ratio selector member (24). The control system includes an electronic control unit (36) which controls the level of clutch engagement in response to an engine speed error signal (E) derived from a comparison of current engine speed (Ve) and a reference speed signal (Vr) generated by the control unit. A sensing means (19a) is provided to detect a "foot-off" condition of an engine controlling accelerator pedal (19) and to provide an indication of the full range of movement of the accelerator pedal from the "foot-off" condition to the fully depressed position. The electronic control unit (36) responds to an accelerator pedal "foot-off" signal to ensure that the reference speed signal is above the engine idle signal by a predetermined amount to prevent creeping of the associated vehicle due to partial clutch engagement at engine idle. In the "foot-on" condition of the accelerator pedal the reference speed signal is switched to a level determined by accelerator pedal position which is close to engine idle speed at low levels of accelerator pedal depression so that the clutch will engage to a torque transmitting level thus allowing the vehicle to be manoeuvred at low engine speeds.

Title: Vehicle door latch
Inventor: BLAND TIMOTHY
IPC: H04W88/08
Filed: 1997-04-02
Abstract: A latch assembly 16 for a vehicle door 10 (FIG.1) hinged at its leading edge, has an L-shaped housing plate 20 to be secured in the trailing inside edge corner of the door and carrying latch mechanism (not shown). Inner skin 14 of the door 10 is cut away to admit a striker 18 into a mouth of the plate 20 for engagement by the latch mechanism to keep the door 10 shut. A projecting abutment rib 28 of the plate 20 adjacent the mouth prevents or resists rearward displacement of the trailing edge of skin 14 which could otherwise obstruct the mouth and trap the striker 18 within the latch assembly 16, in the event of impact damage to the door.

Title: Steplessly-variable ratchet gearing for a chain drive
Inventor: JAGO JOHN JAMES
IPC: B62M9/08
Filed: 1997-04-15
Abstract: A chain or belt drive system which automatically alters the gear ratio according to load requirements comprises a driving wheel (15), a driven wheel having a driving connection (teeth 29) with a chain or belt, and means (23, 25, 27) providing a driving connection between the driving wheel and the driven wheel. The axis about which the driven wheel rotates is movable relative to the axis about which the driving wheel rotates. The movement gives rise to a change in the effective gear ratio and is opposed by a resilient biasing force. The driving connection between the driving wheel and the driven wheel comprises a plurally of driving elements (23) carried slidably by the driving wheel and cooperable sequentially through ratchet teeth with the driven wheel. The sliding connection allows relative movement of the driven wheel with respect to the driving wheel whilst maintaining the driving connection. A cam controls sliding movement of the driving element. The drive system may be used in a bicycle.

Title: Frequency synthesiser
Inventor: SAUL PETER HENRY
IPC: H03B28/00
Filed: 1997-05-01
Abstract: A frequency synthesiser comprises a direct digital frequency synthesiser (DDFS) 11, which provides in phase and quadrature sinewave signals at a preset frequency from DACs 12 and 13 respectively, and a balanced mixer 2. The balanced mixer 2 provides an output signal having a carrier frequency twice that provided by DDFS 1 and reduced levels of spurious signals. A signal having a desired frequency is generated by controlling DDFS 1 to generate sinewave output signals at half the desired frequency. The reduced levels of spurious signals obtained by the arrangement allows improved signals for use in, for example, local oscillator applications. The balanced mixer may be formed by a micro-mixer or by a Gilbert cell.

Title: Valve for aerosol container
Inventor: RIEBE MICHAEL THOMAS
IPC: F16K24/00
Filed: 1997-07-29
Abstract: An aerosol container, for dispensing metered doses of an aerosol formulation such as salmeterol xinafoate medicament suspended in liquefied HFA134a, comprises a valve body 1 having a valve stem 7 through which the formulation is dispensed. The valve stem 7 is sealed by valve seals 9,12 which are made from a peroxide cured nitrile rubber comprising a fluorine-containing polymer such as fluorocarbon polymer polytetrafluoroethane (PTFE) which, due to its low coefficient of friction, acts as a lubricant against the valve stem 7. This ensures a smooth operation of the valve, and reduces the deposition of formulation which can cause valve sticking.

Title: Treating development waste and apparatus therefor
Inventor: SUGAWARA HIROSHI
IPC: B01J41/04
Filed: 1998-11-27
Abstract: A process for rejuvenation treatment of a photoresist development waste mainly containing a photoresist and tetraalkylammonium (TAA) ions comprises waste or a treated solution derived therefrom with a nanofiltration membrane (NF membrane) to obtain a concentrate mainly containing impurities such as the photoresist and a higher-purity permeate mainly containing TAA ions. The concentrate and/or the permeate, preferably the permeate, is desirably subjected to a step of concentration and refining by electrodialysis or electrolysis and/or a step of refining by ion exchange treatment with an anion exchange resin and/or a cation exchange resin in one of the H form and the TAA form. The permeate may advantageously be passed through the concentrating cells of an electrodialysis unit while passing the concentrate through the desalting cells of the unit to further recover TAA ions remaining in the concentrate whereby the amount of wastewater discharged as desalted waste can be decreased. The NF membrane separation step is preferably effected in multiple stages as shown by passing the waste (1) through safety filter (2), first NF (3), the concentrate being sent to second NF (4), and the concentrate therefrom being discharged via line (L3) whilst the permeate therefrom is split with first being returned via line (L1) to waste (1) and rest being combined in tank (5) with the permeate from the first NF (3). Also disclosed is (A) a nanofilter, an electro-dialysis or electrolysis unit and optionally an ion - exchange unit and (B) an evaporation unit or a reverse osmosis membrane unit, a nanofilter and an ion exchange unit (Figs 6 and 7, not shown).

The high voltage electrode (1) has an energy supply rod (2) which is contained in an insulation (3) and which, in an end zone (4) has a non-insulated outer surface (2<SP>1</SP>) passing around the insulated energy supply rod (2). An insulation (6) is provided on the cap (5) to ensure that no flash-over to the cannon barrel (11) can occur. This arrangement avoids erosion and ablation of the barrel (11) by the combustion gases.
